Abstract: | Ethanol extracts of 12 marine unicellular algae were assayed for agglutinating activity against native and enzyme-treated
human and animal erythrocytes. All of the algae assayed agglutinated at least one group of normal erythrocytes from humans.
Notably, all algal extracts agglutinated erythrocytes of hemophilia patients arising from coagulation disorders. Meanwhile,
all algae had a strong reaction with monkey erythrocytes, but to a lesser extent or not at all with sheep erythrocytes. Both
trypsin and pronase improved the detection of most algal agglutinins and caused a drastic increase in hemagglutinating activity
after treatment for 2 h or more. However, hemagglutinating activity decreased or disappeared completely when two extracts
of different algal species were combined. Journal of Industrial Microbiology & Biotechnology (2000) 24, 262–266.
